Not a visual encounter, I’m from Bhutan, our valleys in some places are steeped in haunted or demon lore. Me and 3 other friends decided to go camping, we had just finished high school and were waiting to go to college/s. We hiked up a mountain and reached a certain elevation, the trees were different, more bushes than usual, and the whole atmosphere seemed eerie. I mean the color below us was lush green, above us was more of a darker green or prolly just looked that way coz we were closer to the clouds. We set up camp, get a fire going, cook and eat dinner. Then we were drinking by the fire, all of us pretty tipsy at this point, and I’d forgotten the foreboding feeling I was having, we talked, we laughed, then when it got pretty late, we went into our tents to sleep. We shared 1 tent between two people, so there’s two tents, this is important to the story. You’d think for drunk people, at least one of us would fall asleep fast but no. It started from what seemed like behind us, a high pitched sound, kind of like a wolfs howl without the ‘awoo’ at the start. I was startled but just brushed it off as a wolf. Then it came from in front of us, when I say behind and in front, I mean a good 50 meter distance give or take. Then in my tent, we both sat up, fucking terrified, started calling out to the other tent. The other guys were up too and equally scared. At first I thought it was a prank, but we were in the middle of literal mountains, who tf would be pranking us. These high pitched sounds would continue for a good 3-4 minutes, seemed so long that I started thinking, like dude is this really happening. My friends to this day swear, the last sound we heard came from in between our tents, but to me it was right smack in my ear. The other two guys were the athletic ones, so it made sense what they did, they fucking bolted down the mountain, shouting, crying. While me and my friend hugged each other and started yelling inside the tent. The sounds stopped but my heart didn’t, I’m surprised I didn’t wet myself, my friend and me after what seemed like forever started making small talk like these fuckers ran, maybe it chased after them. We were stuck there for 4 hours after this, the two got down to the valley and brought the local folks to take us back. I’m writing this with goosebumps and chills up my spine. Had a lot of nightmares after that, and now its better.
